Having a shapefile here with 32 houses of a small city, having one attribute 'building year'.
Goal was to have an animated gif in which you see the city grow from a conglomerate of small towns to current city.
Used Dimensions/Elevation/column 'buildingyear' for use of dimensions.
Most stuff works: I can get one year of building, and even the animated gif is working wit individual years like:
http://localhost:8080/geoserver/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=132739.5089999999909196,446484.10038488148711622,137324.91500000000814907,452288.22286230162717402&SRS=EPSG:28992&WIDTH=445&HEIGHT=561&LAYERS=panden&STYLES=polygon&ELEVATION=1900,1920,1940,1950,1960,1970,1980,1990,2000,2010,2020&format_options=gif_frames_display:200;gif_loop_continuosly:true&format=image/gif;subtype=animated
(panden1.gif)
Then the I tested ranges:
http://localhost:8080/geoserver/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=132739.5089999999909196,446484.10038488148711622,137324.91500000000814907,452288.22286230162717402&SRS=EPSG:28992&WIDTH=445&HEIGHT=561&LAYERS=panden&STYLES=polygon&ELEVATION=1900/1950,1950/2000,2000/2100&format_options=gif_frames_display:200;gif_loop_continuosly:true&format=image/gif;subtype=animated
yes, working: panden2.gif
BUT the goal is to see 'the city grow' so I want to add the new range on top of the old range. One solution for this, is to have 'overlapping' ranges, like:
1900/1950,1900/2000,1900/2100
http://localhost:8080/geoserver/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=132739.5089999999909196,446484.10038488148711622,137324.91500000000814907,452288.22286230162717402&SRS=EPSG:28992&WIDTH=445&HEIGHT=561&LAYERS=panden&STYLES=polygon&ELEVATION=1900/1950,1900/2000,1900/2100&format_options=gif_frames_display:200;gif_loop_continuosly:true&format=image/gif;subtype=animated
see panden3.gif
BUT now geoserver will not generate an animated gif anymore, but it looks like it 'inteliligently' concludes: "hey all together that is form 1990 to 2100, so let's just sent ONE image with all house?
So question: is this by design? Or is it a bug?
If in need of testdata, just sent an email to rich...@duif.net and I will sent you this shapefile
